The game features elaborate, large randomly generated maps filled with interesting terrain, roads, towns, factories, and mines. Roads and tracks can be placed, along with depots, stations, signals, and road upgrades. Operating functioning, profitable lines requires tedious vehicle replacement that should either be automated or more streamlined. The game’s resource flow is very simple: four resources are found at mines, and then manufactured into generic “goods” at factories. The passenger and cargo simulations (they will use mass transit if its faster) are more complex. Towns will grow in response to your development decisions, although the simulation runs slowly even on the fastest setting. Train Fever is a relatively simplistic simulation that lacks the sophistication required for long-term enjoyment.
